CTA 500

dm

The CTA 500 digital modem (CTA 500

dm

) is an optional device

used with the Norstar Integrated Communication System (ICS).

With ICS software, using release 2.0 or higher, the CTA 500

dm

provides integrated desktop solutions for digital networking

applications. With optional Norstar Telephony API Service Provider

(TAPI SP), the CTA 500

dm

also supports Computer Telephony

Integration (CTI) services required for today's ofÞce environment.

With the CTA 500

dm

you can access remote computers on networks

including the Internet. You can also telecommute over a digital

telephone network and access the CTA 500

dm

in your ofÞce. The

CTA 500

dm

allows you to access high-speed network features in

your ofÞce from your home telephone.

The CTA 500

dm

serves as a digital modem and terminal adapter

(TA). A terminal adapter is a device that allows non-ISDN devices

to work with ISDN. It provides reliable high speed end-to-end

digital connectivity between your computer and a remote data server

using the ICS and the public switched telephone network (PSTN) or

Integrated Services Digital Network (ISDN). The CTA 500

dm

supports Point-to-Point Protocol (PPP) and Multilink PPP (MP),

which are widely supported by Internet service providers (ISPs) for

Internet access and corporate data communication networks

(Intranets) for remote LAN access. PPP and MP are supported as

built-in features of Windows95.

You can also connect a Norstar telephone to the CTA 500

dm

to

access Norstar voice services. You can use the same telephone line

to simultaneously carry on a conversation while your computer is

connected to the Internet or remote LAN with no loss of ICS

features. The CTA 500

dm

connects to the ICS using standard

telephone cabling.

MP works with intelligent bandwidth management software in the

ICS to provide dynamic bandwidth allocation accessible at your

desktop. Norstar station interfaces support two channels that are

ßexibly allocated to transmit data, voice, or both. When the attached

Norstar telephone is not in use, all bandwidth is allocated for data

trafÞc (up to 128 kbit/s). However, if you want to use the phone to

answer an incoming call, or place a call using the free line or the

intercom, one channel is automatically allocated for the

conversation and the data connection continues at 64 kbit/s. When

you hang up the telephone, the second channel is automatically

reallocated to the data connection.

Using a CTA 500

dm

compliant Norstar TAPI Service Provider, the

CTA 500

dm

allows simultaneous PPP/MP data connections and

TAPI computer telephony integration (CTI) applications on your

PC.

In addition, some of the ICS resources normally used for voice

applications, such as network access lines and calling line features,

can be used for data trafÞc. Network access lines can be shared

between CTA 500

dm

s and other trafÞc within the system. Features

such as call logging, call restriction, and routing based on time of

day can be applied to data trafÞc for facility utilization and

management.

On Line Guide

Any PC equipped with Windows95, Internet application software,

and a 16550 UART (115.2 kbit/s capability) can use the

CTA 500

dm

.

Applications

The CTA 500

dm

can be used for any application that requires

dial-up capability and uses Point-to-Point Protocol.

These applications include

¥ Internet access

¥ remote LAN access

¥ high-speed modem replacement

¥ CTI based applications when Norstar TAPI SP is added

¥ data transmission at up to 64 kbit/s on either channel of an ISDN

link or 56 kbit/s on a T1 trunk

¥ supports Multilink PPP to enable the dial-up connections to use

two channels

Internet access

The CTA 500

dm

allows Norstar customers using digital network

interfaces on the Norstar ICS to access Internet service providers

(ISPs). You can connect an ISP through the public switched digital

network (PSDN) using regular dial-up methods.

Dial-Up Networking

You can use the CTA 500

dm

for remote LAN access applications

when PPP is used to connect to a remote LAN.

Data-to-data transfers

The CTA 500

dm

can be used to establish a connection with an ISDN

Terminal Adapter (PPP or MP must be supported) or another

CTA 500

dm

for Þle transfer. You can connect two computers to the

same ICS through their own CTA 500

dm

units, or connect them

through the network. Using the CTA 500

dm

connection allows

analog modems to be replaced with high-speed digital connections.

The CTA 500

dm

does not support connection to analog or 56k

modems.

Computer Telephony Integration (CTI)

With a compliant Norstar TAPI SP, the CTA 500

dm

allows

simultaneous sessions of PPP/MP and CTI based applications to run

on PCs.

Setting up the ICS

Program the ICS for the CTA 500dm the same way that you program

the ICS for a Norstar set. You can program line access, line pool

codes and restrictions to apply to outgoing calls. The CTA 500dm

must be assigned to a digital line or to a digital line pool. Refer to the

ÒTerminals and sets programmingÓ section of your Installer Guide

for more information.

The CTA 500dm is a B2 channel device and must be assigned a B2

channel DN. The following table shows the default directory

number (DN) that is assigned to the CTA 500dm based on the

physical set port that connects the CTA 500dm to the ICS.

You can change the DN that is assigned to the CTA 500dm in the

same way that you change a DN for a Norstar telephone. Refer to

ICS Installation Guide for more information.

Note: If you use automatic telephone relocation (set relocation) to

change the port used by a CTA 500dm, you must power down

the CTA 500dm before changing the connections. If the

CTA 500dm is not powered down, programming information

will be lost. See ICS Installer Guide for more information

about set relocation.

Installing Norstar TAPI SP

To use a CTA 500dm for TAPI applications, Norstar TSP must be

installed. It can be installed at the same time as the CTA 500dm

software via the Personal Productivity Suite (PPS) installation

procedure, or it can be installed later from the PPS CD.

Note: The current CTA 500dm conÞguration does not support

dynamic bandwidth allocation if you donÕt have access to a

line pool with more than two ISDN lines. When you are

making an MP data call and want to make a voice call at the

same time, lift the telephone handset in order to make a

channel available for the call.

Conﬁgure TAPI dialing properties

If you use an access code to get an external line or get a private

network line to make a long distance call (for example, dial 9 before

dialing an external number or dial 6 before dialing a long distance

number), you need to conÞgure the Norstar set attached to the CTA

500dm.

1. Click the Start button and move the cursor to Settings.

2. Choose Control Panel from the sub-menu.

3. When the Control Panel window displays, double-click the

Telephony icon.

4. When the Telephony Properties window displays, click the
